A very popular, unusual design in fine silver (999) it reminds me of an ammonite. With added patina; (bluish background) or with gold plated highlights and no patina; with or without freshwater pearl dangle A perfect gift. Please contact me via the contact form to discuss further. Weight 6 gms approx Size 2.5 cm square approx I do not provide a chain with necklaces or pendants. Most people have a favourite chain and chains are interchangeable. I now have two or three which work for most of my silver pieces. II use Cookson Gold http://www.cooksongold.com/Finished-Chain/ here you can chose the length and style and the finished chains are very affordable. For a really beautiful Italian made snake chain visit www.boothandbooth.co.uk and take a look. Great service and beautifully made chains and relatively inexpensive.
